If the executable exists already, why am I typing in the source code
in Emacs? :-)
gcc -E can expand the macros just fine, it just needs the same input
(-I -D and -U) as gcc got when creating the executable. As others
pointed out, it is impractical to set this up if you are working on
several different projects at once.
Personally I don't see the need for expanding macros. One of the
reasons I use them in the first place is to hide details I don't need
to see. Expanding them while editing seems a strange thing to do.
